JACOB M. LONDON, OF TUNNELTON, PENNSYLVANIA, ASSIGNOR, BY DIRECT ANDMESNE ASSIGNMENTS, OF ONEFOURTH TO GEORGE M. CRAWFORD AND ONE-HALF TOEMIL M. REFIOR, BOTH OF vITTSBURGH, PENNSYLVANIA. l

vTo all whom t may concern:

Be it known that I, JACOB M. LONDON, a citizen of the United States,residing at Tunnelton, in the county of Indiana and State ofPennsylvania, have invented certain new and useful Improvements in CoalA object of the invention is the-novel manner of mounting t'he cuttingmechanism for movement so that a cut may be made of a width equal to thewidth of the mineand of any depth necessary. f

Another object of the invention is the use of means for supporting thecutters at dif- I ferent heights so as to accommodate varying width ofthe vein of coal.

Besides the above my invention is distinguishedv in the construction ofthe mount'- ing for the cutters so that the cutters ma)Y be quicklyadjusted to a plurality of different positions and vibration thereofprevented. y

lVith these and other objects in view the invention will be 'betterunderstood from the following detailed description taken in-connectionwith the accompanying drawings wherein v v Figure l is a side elevationof the machine. Fig. 2 is a top plan view thereof.

Fig. 3 is a rear elevation of the machine.

Fig. 4 is an enlarged sectional view through the coal conveyingmechanism.

mechanism for the necessary movements, the latter having a turn tableconnection D with a truck E movable on suitably arranged rails F in themine.

The coal cutting mechanism consists of a f platform 1, mounted forrocking movement upon the frame by means of a saddle 2, that forms a`connection between the platform and the frame (l.M In-this particularinstance the saddle as shown in Figs. 5 and 6 consists of arcuate shapedribs 3 carried by the frame and platform and having interlockingengagement with each other as indicated at From this arrangement it willbe seen that with very Vlittle exertion the platform may be rocked to aposition whereby the upper surface o f the platform maybe arranged at anangle extending in any direction.

After the platform has been moved to the proper position it is held inthis position by bolts 5 that have a swinging connection with the frame'l andclamp to the platform by tightening the nuts thereof.

Mounted within the platform is a guide (3 with which cooperates theroller 7 on a guide pin 8 that is 1n turnrigidlv connected to the coalcutting carriage 9. The purpose of this latter construction is to form apivotal as well as a slidable connection between the carriageQ and theplatform, for a purpose hereinafter described.

Also mounted within the platform 1, is' a toothed track 10 of aconfiguration identical with that of the cut that is made by the coalcutting mechanism and at this point I wish to call attention to the factthat this track 10 may be of any other suitable outline dependingentirely upon the shape of the cut to be made.

A gear 11 that has a slidable connection with the cutter drive mechanismto be described later engages the trackv 10 and is held againstdislocation therefrom by a of the gear 11. From this arrangement it willbe seen that the movement of the carriage 9 along the platform 1, isconfined to thel Outline of the cut made by the cutting mechanism and insuch a manner that thev number of parts ynecessary is reduced and .wearminimized.

.'The carriage 9 consists of an upper part or section 13 and a lowersection V14 that slides upon the platform l. vThese parts are connectedand mounted for adjustment relative to each other by means of the screws15, shown in this particular instance as four in number, one at eachcorner. of the carriage .and each having screw threaded engagement withone part and non-threaded engagement with the other part.

At this point I wish to call attention to the fact thatalthough screws15 are shown because of the power that can be accomplished thereby othersuitable devices may be used for separating the parts for givingadjustments to the cutting mechanism now to be described. v

This cutting mechanism consists of a ba 16 extending horizontally fromthe carnage withone end rigidly connected to the section 13. Mountedwithin the fixed end of the bar is a sprocket wheel 17 cooperating withthe sprocket wheel 18at the free end of the bar for giving 'the propermovement to the chain 19 to'wliich, is secured at suitably spacedintervals the cutters 20.

Mounted Within the carriage is an electric motor 21 having driveconnection 22 with the sprocket 17 and this drive mechanism may includeaclutch 23 for reasons Well known. This'drive mechanism includes a .pairoli gears 24 and 25 coperating with a gear 26 slidably mounted on theshaft of' thegear 11 whereby the latter may be driven at two di'erentspeeds for a purposehereinafter described.,

To complete the coal cutting mechanism I connect the screws 15 in pairsby means' Y of chains 28 passing over .sheave 'wheels 27 one of .whichis fxedly mountedon each of' the screws 15. If found necessary inpractice this shaft may be formed in sections connected together byfriction clutches as illustrated. at 32 for obvious reasons. l

From the foregoing description it will, be seen that by constructing andassociating the parts as described the coal cutters 20 and .bar 16 maybe arranged at a multiplicity of angles and elevations; that is to sayby adjusting the parts 13 and 14 relative to each other for raising andlowering 'the cutting mechanism or rocking the platform, 1, upon thesaddle 2, and rigidly securing the same in'veither ci its tour inclinedpositions by bolts 5, y

A very important feature oit my coal cutting apparatus is'that onesource of power -is capable otxsimultaneously feeding the carriage inthe proper direction and `operating the cutting mechanism and in such amanner thatthecvutting apparatus may be quickly .removed from -they,iframe C by simply removing vthe pin 8' and raising thecuttingapparatus as a unitvertically. The

advantage of driving the gear 11 at two speedsisnow obviens as duringthe cutting remota feed the same to the rear of: the machine.

This apparatus consists of a carriage 33 including a bearing 34pivotally connected to a block 35 slidably mounted upon the frame 1 andautomatically moved 'in a manner to be described later.

Fixed to the carriage 33 is an electric motor or othersuitable primemover 36, the armature shaft 37 of which' has one end associated with a`pair of Worms 33 and 39 .the former driving the conveying means to bedescribed later, and the latter cooperating with a gear 40 lixed upon ashaft 41 that also has .fixed thereon sheave wheels 42 and 43 aroundwhich pass chains 44 directed around idlers 45 and connected-to theblock 35. From this arrangement it will be yseen that when the clutch 46arranged on the shaft 41 is operated, movement will be transmittedthrough the chains 44 toI the block 35 andas a'result the carriage33`and the conveying means now to be described thereon will be movedtoward and away from the pile of coal depending entirely upon thedirection of rotation of the-motor.'v

Theremainingend of the armature shaft has a gear connection 47 with apair of parallel shafts 48 and 49 .each supportingl a bevel gear 50.Associated with each of the beveled gears 50 is a coal'feeder 51consisting of an upper rake device 52 and a lower rake device 53,theupper havingthe larger capacity. lEach rake device consists of aplurality of teeth or Scrapers 54 lcarried on an endless belt or chain55 driven in any suitable manner by Ithe shaft56 that receives itsmotion through a beveled gear 5f? rigidly secured thereto vand engagingthe beveled( .gear 50.'.

i The frame 58 of each of the feeders is priivided with a bearing 59supported for rotation upon one of the heretofore mentioned parallel'shafts sofas to swing vertically in the arc of a circle as shown indotted lines in ligg9. For the purpose of swinging the l feeders to thisdotted position, a cable 60 is provided lor each feeder having one endconnected directlyl to the feeder and trained around suitable idlers 62and then passed around a drum 63 thatl hasa clutch connec` tion with the.shaft 4l; thus-it will be vseen that the machine may be readilymovedinto and out of a mineand quickly arranged |in 'an operative position. c

4 At this point llwish'to'call/attention to iro the vfact that by theuse of this swinging connection of the feeders, the cable 60, and thelpivotal connection lbetween thecarriage 33 and the frame l, thefeeders' may be 'arranged in a plurality of positions so asto insure theproper coperating ofthe feeders and the lowermost particles of adislodged pile of coal. a

.This 'manner of acting upon the pile of coal b*T the feeders causes themajor portion of the pile vof coal to fall by gravity as the feedersonly eXcavate a certain amount of coal from under the pile of coal andgravity is relied on for the major portion of the pile to gravitate'upon the conveying means now tofbe described.

Arranged directly over the feeders is a shield 64 for preventing thefalling -coal from interfering with the operation ofthe feeders. Workingdirectly under4 the' feeders is a scoop 65 that is carried by thefrontend of a series of conveyers, two of which, 66 and `67 arepivotally supported atfS'upon 'the carriage 33. The remaining conveyers68a, 69, and 70 are pivotally connected to' each other as indicated at7l andfmounted upon a.v second truck 72 also traveling on the rails F.This truck 72 is connected to E by the chain 73 and the conveyersSa, 69and 70 may be associated with or removed from the conveving meanscarried bv the carriage33. l l

The conveyers of this'portable conveying l apparatus are adapted to beoperated by an electric motor 74 while an adjusting device 75 isprovided to raise and lower the conveyer for regulating the feed of coaltherefrom into a coal car in the rear. The

conveyers 66 and 67 have a drive lconnection 76 with the worm 38.

If found advantageous in practice the turn table D may be mechanicallyoperated by a worm shaft 77 that engages the rack bar 7 8' secured toone of the disks of the turn table, and -this worm shaft 77 is' drivenin any suitable manner as shown diagrammatically at 79. 'v

To complete the invention I arrange at suitable points jacks 80pivotally connected to the frame and adjustably engaging the wall of themine.

It isV to be understood that while all of the several features of myimproved coal cutting and loading apparatus have special' coperationwith one another and 'together constitute a particularly effectivemachine for-the purpose in view certain of these features may be appliedin other relations and I therefore desire to cover the combinationspresent in the several parts of my machine whether employed in thegeneral organization shown or elsewhere.

It is further to be understood that the structural embodiment of theinvention as awhole and its various features as shown is merelyillustrative and not Vrestrictive since I am well aware that many of thedetailsof construction can be widely varied without departing from thespirit of the invention. I therefore do not desire to be limited in thisconstruction or in any other except-as set forth in the appended claims.
